塑料 未增塑的乙酸纤维素 水分含量的测定

[中文适用范围]： 计算分析方法中使用的干质量可能需要进行此测定。 仅适用于水分含量不超过10%的产品。 其原理是将测试部分在恒温箱中于105℃下干燥，然后称重。 根据测试部分的质量损失计算水分含量。 取消并取代第一版 ISO 585:1982，它构成了一个小修订。 [外文原描述]： This determination may be required for the calculation of the dry mass used in analytical methods. Applies only to products with a moisture content of not more than 10 %. The principle consists in drying a test portion at 105 ° centigrade in a thermostatic oven, then weighing. The moisture content is calculated from the loss of mass of the test portion. Cancels and replaces the first edition ISO 585:1982, of which it constitutes a minor revision.
